msxml stylesheet for displaying xml tree question

This is really sort of off-topic, I was thinking I might like to improve
my defaultss.xsl version I have, to do some of the things I want I need
to add some extension functions, one of which would be a function that
finds where the xml document that the xslt is displaying is located at
(remember that defaultss.xsl is a resource in the .dll) anyone have
suggestions on the best way to do this? Perhaps there's some hidden
objects/methods/properties exposed to the scripting environment for
extension functions in msxml that someone out there knows about?
